trum; but I believe that that genus should be merged in Sphaeral- 
cea. Malvastrum coccineum, the type of the genus, has the habit 
of the typical species of Sphaeralcea. The fruit is also the same 
except that the empty non-reticulate portion of the carpel is 
much reduced. M. grossulariaefolium and M. Munroanum with 
little more developed upper portions have been tossed back and 
forth between the genera Malvastrum and Sphaeralcea. Six species 
should be transferred from Malvastrum to Sphaeralcea under the 
following names.
